JESSE G. VINCENT, OF DETROIT, MICHIGAN, ASSIGNGR T0 PACKARD MOTOR CAR COMPANY, OF DETROIT, MICHIGAN, A CORPORATIN OF MICHIGAN.

HYDROCARBON-MOTOR.

To all whom t may conce/m:

Be it known thatl, Jnssn G.' VINCENT, a citizen of the United States, and resident of Detroit, lVayne county,State of Michigan, have invented certain new and ,useful Improvements in Hydrocarbon Motors, oi' which the following is a specification.

This invention relates to hydrocarbon vmotors and particularly to the construction and arrangement of the cylinders and intake and exhaust passages. l

LOne of the objects of the invention is to so form the intake and exhaust passages in the motor cylinder blocks as to facilitate manufacture thereof.

Another obj ect of the invention is to forni the intake passages oi the cylinder block vwith asl few turns as possible while at the same time providing for heating the passages from the exhaust passages.

Another object of the invention is to arrange the intake passage of a cylinder block in the cylinder casting with a single communication through the cylinder head casting to the intake pipe.

Another object of the invention is to arrange the exhaust passages of a motor' cylinder block so that free egress for the gases is obtained while at the same time the intake passages are properly heated.

Other objects of the invention will appear-from the following description taken in aonnection with the drawings, which form a parl of this specification, and in which:

Figure 1 is a vertical transverse sectional view through a V-type motor embodying the invention;

Fig. 2 is a part elevation and part longitudinal sectional View through one oi the cylinder "blocks shown in Fig. 1, the section being substantially on the line 2-2 of Fig. 3; and

Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

Referring to the drawings, 10 represents a motor crank case upon which are mounted a pair of cylinder blocks C. It is intended that each entire block including its cylinder' and head castings and other appurtenances shall be referred to as a cylinder block and indicatedv by the reference letter C, but in some Specification of Letters Patent.

Patented Sept. 14, 1920.

Application filed December 17, 1917. Serial No. 207,560

instances the cylinder casting alonernay be hereinafter referred to as a cylinder clock. But one oi the two cylinder blocks will be described in detail and it will be understood that they are alike inlall essential particulars except of course that the valves and gas passages are on the right handside of the left block and on the left hand side of the right block.

The essential parts of each of the cylinder blocks are a cylinder' casting 11 anda detachable head listing 12. These blocks are mounted upon the crank case 10 in V-arrangement as shown in Fig. 1 and within each of the cylinder bores 13 is a piston 14 operated by a connecting rod 15, the latter being connected to the crank shaft of the motor, not shown.

A series of ports, both intake and exhaust, are arranged in the cylinder casting along one side of the cylinders, the intake ports being indicated at 1,6 and the exhaust ports at 1T. These ports are provided with valves 1S and 19 respectively, the latter being controlled by springs 2() and push rods 21 from a suitable cam shaft mounted in the crank case and not shown. For the operation of the motor spark plugs 22 are suitably provided in communication with the combustion chamber 23 formed above the piston 14. Also, the cylinder and head castings are formed with suitable water jackets 24C and 25 which are supplied with cooling water ports 17 to the outside or outer face of thev block. There these passages are in communication with various openings 29 in a detachable exhaust pipe or header 30. There are of course two of these exhaust pipes 30 and they extend lengthwise of the two cylinder blocks C and in the V formed by the blocks. This arrangement of exhaust passages provides very free egress tor the gases from the combustion chamber through the exhaust ports 1T.

Arranged directly bmeath the lateral exhaust passages 25 is an elongated intake conduit ill, parts oi' the walls of said passages 28 forming parts of the upper walls of said intake conduit so that the heat from the exhaust gases passing through said passages 28 directly transferred to the conduits 3l to thereby heat the incoming gases therein` Upon reference particularly to Fig. 2 it will be seen that there are two of these passages 3l for each cylinder block when a block of six cylinders is used as in said figure, and these conduits 3l have vadjacent upturned ends as at 32 which extend the conduits up to the upper surface of the cylinder casting. At this point the head casting l2 is formed with a pair of intake passages 33 therethrough, which passages are respectively in register with the ends of the intake conduits 3l of the cylinder casting.y An integral extension 34 on the head casting carries the passages upwardly somewhat, as shown particularly in Figs. l and 3, and an intake pipe 35, shown as of arched formation, connects the two extensions 34 of the respective cylinder blocks as shown in Fig. l. The intake pipe 35 carries a carbureter 36 and it may if desired be formed with a passage 3T and an outlet 38- for the water from the water jackets of the cylinder' blocks. lts main passage 39, however, conveys the combustible mixture from the carbureter 3G to the passages 33 in the head casting and thence downwardly through the upturned ends 32 into the in take conduits 31.

At the right in Fig. l it will be seen that there is a diagonally extending branch passage l() leading` from the intake conduits 3l to each of the intake ports 1G so that the combustiblev gas is conveyed directly from the conduit 3l to said intake ports. Thus the incoming gas has but two distinct turns to make from the time it leaves the intake pipe 35 until it passes one of the ports 1G',-

that is, the turn where it passes frointhe passage 3Q to the conduit 3l and the second turn where it passes from the latter conduit to the direct passage 40.

lt will be understood further that Iny invention is not limited to the details of construction shown and other forms may he used without departingfrom the spirit or scope of the invention.

Having thus described my invention, what l claim and desire to secure by Letters Patent is l. A motor cylinder block having a series of intake and exhaust ports in line. and having walls forming conduits which lead separately and laterally from the exhaust ports to the outer face of the block. the said block having a longitudinally extending intake conduit therein common to said intake 'ports and into which said walls of the lateral con duits of all of said exhaust ports extend.

2. A motor cylinder block having the following ports and conduits formed therein: a series of intake and exhaust ports arranged in line, an intake conduit running lengthwise of the block adjacent the valves, branch conduits from said intake conduit to the various intake valves, a branch conduit leading from the top of the block downwardly to the intake conduit, and exhaust conduits leading laterally away from the exhaust ports, the walls of said exhaust conduits projecting into said intake conduit.

3. In a hydrocarbon motor, the combination with a cylinder block, of a detachable head therefor, said block having an intake conduit extending lengthwise thereof and turned upwardly at one end to thehead, and said head having an intake passage therethrough registering with the intake conduit in the block.

4. In a hydrocarbon motor, the combination with a cylinder block, of a detachable head therefor, said block having an intake conduit extending lengthwise thereof and turned upwardly at one end to the head and having exhaust passages extending laterally to the outer face of the block, and said head having an intake passage therethrough registering with the intake conduit in the block.

5. ln a hydrocarbon motor, the combination with a cylinder block, of a detachable head therefor, said block having two alined intake conduits extending lengthwise thereof and turned upwardly at adjacent ends to the head, and said head having a pair of adjacent intake passages therethrough registering with intake conduits in the block.

6. In a hydrocarbon motor, the combination with a cylinder block having a lengthwise extending intake conduit with an upturned end and having laterally extending exhaust passages, of a detachable head for the block having an intake passage therethrough registering with said upturned end, and a detachable exhaust pipe adapted to connect with said exhaust passages.

7. A motor cylinder block having the following characteristies: a plurality of valved intake and a` plurality of valved exhaust ports arranged in line at one side of the ovlinders, exhaust passages leading from the exhaust ports laterally directly to the outsidc of the block, a longitudinal exhaust pipe outside of said block and communieating with said passages, an elongated intake conduit within the block arranged directly beneath the exhaust passages so that parts of the falls of said passages form parts of the upper walls of said intake conduit. and intake branches leading from said conduit to the intake ports.

j 8. In a hydrocarbon motor, the combination with a pair of adjacent cylinder bleks each comprising a cylinder casting and a detachable head casting, and each cylinder casting having an -intake conduit extending lengthwise thereot` with an upturned end, and each head casting having an intake passage therethrough registering with the upturned end of the intake conduit of its respective cylinder eastingand aniiitake pipe connected to both of said head- Castings and l0 registering with the intake passages therein.

In testimony whereof I afiix my signature.
